We are already above 30% in some polls. I think it is also fair to say that the momentum is with us. Imagine what could happen if more and more people realised that an historic breakthrough is possible.

Now I don't want to get carried away here. Many activists like me are gobsmacked at how quickly we have jumped from c20% to c30% of the vote and are just hoping that the current numbers can be sustained let alone anything else. However I think this polling question demonstrates that it would at least be possible for us to do even better than we are at the moment.

UPDATE 10:23: Having been asked in the comments I have now been given a link to the data for the numbers referenced above. It is here. (Note: opens PDF)

This has been the case for every election for the last 30-40 years, apparently.

Nick really needs to hammer this home in every speech, every answer he gives from now on. Our strategy now should be to emphasise that only the Lib Dems can win the election outright - because that's what this surge means.
